I’m just about to have a go at one of the larger boards – the ESP12 (or 201)… so can someone save me (and others) re-inventing the wheel. Here’s what I do to initialise an ESP-01 port bit GPIO0 as an output. Firstly the setup.. // For GPIO2 just change…

I don’t want to jump in prematurely here but those of you who have been reading the blog will know that I’ve had no end of problems with the MQTT stand-alone software on the ESP8266, but as each problem has emerged, the author (Minh Tuan) has been keeping in touch…

ESP8266 MQTT and LOSS OF WIFI

January 31, 2015September 5, 2020 Peter ScargillESP-01, ESP82669 Comments

Update at 13:22:00 on 02/02/2015 This morning I had an email to say the WIFI loss was fixed in the MQTT code. I downloaded the latest MQTT software and put my code back into it. I turned the WIFI off for a few seconds then back on – that worked,…

All I have time for right now, here’s the new board, the ESP-01 (left) next to it should give you an idea of the size of both the development board and the ESP8266 board that goes into it – NOT SMALL. And yes, those are 0.1” centres. No points for…

So… here’s where I’m up to with my little project… currently stalled until we can figure out why the ESP8266 is not recovering from loss of WIFI. This is “the plan. Using the basic MQTT code, I’ve added the ability to control GPIO0 and take input from say a Dallas…

SOLID STATE MINI-RELAY FOR ESP8266

January 27, 2015January 31, 2015 Peter ScargillESP-01, ESP826619 Comments

The PR26MF22NSZ and it’s larger cousin the PR39MF22NSZ are miniature 8-pin devices which look for all the world like any other 8-pin chip – but are able to switch mains power at up to 0.9amps – i.e. up to 200w. Seems unbelievable but that’s the claim – sensible you could…
